yo-yo. the prices go up, they come down, go up, come down again. crude prices are on the rise. they look like they're heading toward the $100 a barrel mark. the crude is rising despite the fact the u.s. and other countries agreed to release millions of barrels of crude from their emergency reserves. the u.s. has agreed to release 30 million barrels. that sounds like a lot, but really, if you think about it, 30 million barrels is less than two days' worth of the domestic consumption in this country. it really is just a drop in the bucket. why are prices going up? there are a couple of different reasons. summertime, of course historically we see a demand increase, and that, of course, rises the prices. and also, the economies around the world are showing signs of improvement, which, of course, is good news, but one of the effects that happens here is that the demand for gasoline goes up as people are doing better, feeling a little more optimistic. they begin to spend more, and the demand for gasoline goes up. that raises concerns about supply, and all of that, unfortunately, causes the prices to increase.
